TE A E PATENT mm LEwks'swiNnELL HOPLEY, or HARTFORD, CONNECTICUT,ASSIGNOR 'ro ROYAL TYPE- ,JQYBIIER COMPANY, on NEW YORK, N. Y., ACORPORATION OF NEW JERSEY.

Be it known that I, LEWIS SWINDEIJL HOP- Lor, a citizen-ofthe UnitedStates of America, residing in Hartford, county of Hartford,- State ofConnecticut, have invented ccrtain 'lmprovements in- Type-WritingMachines, of which the following is a'specification.

This invention relates particularly to machines such as those known inthe market as the Royal Standard in which the type bars are pulled tothe printing point by a connection composed of two links hinged togetherat their adjacent ends, one end of the connection being connected-to theheel of the type bar and the other hinged .to a fixed P011113 on theframe. Such a'machmeisillus; trated inpatent to Edward B. Hess, No.

700,687, dated May 20,1902. The type bars are actuated by push pins tothe lower end of each of which are hinged two links one extending to afixed point on the frame and the other extending rearwardly to itscorre- The links in such ma-' spending type bar. chines have usuallybeen made of piano wire and in applying their ends to the push pin andto the type bar and fixed point respec tively, it has been customary tobend the wire to form hooks at its ends; and to insure itspermanentengagement the hook is practically closed. Even then under longcontinued use there is a tendency for the wire,

hook to pull out and for the link to disengage the part with which it isconnected.

This invention comprises a specific improvement in the construction ofsuch links.

In the accompanying drawing: Figure 1 is a bottom plan View showing onepair of links, the anchor point for the front end of the front link, theend of the push pin and the under face of .the finger piece appliedthereto: Fig. 2, a view of the front link 2'. e. the one that extendsfrom the end of the push pin 'forwardly to the anchor point:

1, in Fig. 1 indicates the bottom face of the fixed plate locatedbpneath the key board from WlllCll are punched on ,three sidesdownwardly turned lug's2 havin gapertures for connection with links 3.The links 3 at their front ends are each formed by bending the wireabruptly so as to form a seat 4 for the walls of the aperture in the lu2. Beyond this seat, the end 5 of the wire is inclined slightlyrearwardly. The rear end of the link 3 is bent in a circular curve as at6 into parallelism with the adjacent body of the link, and its end ispreferably flattened. At. the front end of the'hnk, the outer curvedpart of the wire, the curve of which is formed by bending over theend-to form the seat 4. is swaged upon both sides by power exerted atright angles to the plane in which the-hook 4, 5 is dis os'ed, therebeing thus formed a flat latcike'or rib-like part 8.

An elevation 0 such a link,'looking at the edge of'the swaged part 8,the link appears straight,that is all of. its parts are in the sameplane; but as viewed at right angles to Fig. 4 that is, as sen in-Figs.1 and 2 part of the link in'front' of the point 00 is deflected slightlyso as to be oblique to the part in rear of that point. The deflection ofthe forward part of the link is in the direction of that side ofthe linkupon which is formed the hook 6, 7. Such particular shape of the body ofthe link is considered advisable as it tends to retain the link in.engagement with the lug 2. p

In Fig. 1', 9 indicates the finger piece of a push pin of which '10 isthe stem. .The

' hooked rear end'of link 3 is engaged in an aperture in the stem. Thefront hooked end 4, 5, is engaged in the'aperture ingthe lug 2. Inassembling the machine, the hook 6, 7, is engaged with an aperture inthe push pin stem, and then theli1j1k3 is strained toward the front ofthe machine imtil its. fronthooked end-may be inserted in the aperturein lug 2. Ex erience has demonstrated that the link will not disengageits push'pin 10 or lug 2, and that the swaging of that part of themetalforming the circumferential part of the curve produced in forming thehook et, 5, imparts such'rigidity and strength as to'prevent the hookfrom straightening out, or being distorted to such disengagement fromthe lug 2. v

Figs. 5 and 6 indicate a slight modifier tioii of construction in whichthe hook that engages thelug 2 is not so bent as to form the straight orflat seat, but is on the contrary a circular bend in the curve. of whichthe wall of the lug 2 lies. The link 11 that extends rearwardly fromthepush pin 10, has at its front end a hook, similar to that at the frontend of link 3, for engagement with an aperture in the stem shown asbeing below that one with which the link 3 engages. There is aninclination of that part of the link 11 in front of the point an si1nilar to that which the link 3 has. Beyond the point a;-,' the link 11is'straight. It is however shown broken away. Its rear end will,however, be formed with a hook to engage-an aperture inthe heel of thetype bar (not shown); The part marked 12 in Fig. l is a hanger clampedupon the link 11 in the manner set'forth in the patent of M. H. FlynnN0. 8855742April 28, 1908, and from which extends rearwardly' a link 13that operates the universal bar of the machine.

1. A wire type-bar operating-link havin its end bent to form an engaginghook and the outer circtmifercntial part of the bend forming the hookswag-ed in the plane of the hook.

2. A wire type-bar operating-link bent at its respective ends inopposite directions to form engaging hooks and having the metal formingthe outer circumferential part of one of the hooks swag-ed in the planeof the hook.

A wire type-bar operating-link bent at its respective ends in oppositedirections to form engaging hooks and having the metal forming thecircumferential part of one of the hooks swaged and the swaged end ofthe link inclined to the remainder of the link in a direction towardthat side upon which is the other hook.

In testimony whereof, I have hereunto subscribed my name.
